Jim,
I think the Dart is only a 1/8 hp pump. Can't hold much pressure and cuts off at 12 ft head.
3/4 hp pump is huge, probably in the 450 watts + category.
Reefbuilder, let us know how much head pressure you'll be dealing with. We can then recommend a different pump if the Dart doesn't meet your needs. With the information you gave, the Dart is a great pump that will cost you less to run. If you're dealing with a minimum of 10' static head, the Barracuda might be more appropriate.
Either way we can get you any of the Sequence pumps, or any other pump you might be looking for.
